Description

  The present invention relates to a soil culturing device that is attached to a soil cultivator frame that is pulled by a tractor or the like and performs soil cultivation work for crops, and more particularly to a soil cultivation device that can be shared by different soil cultivation operations depending on the type of crop and the growth process.

A soil cultivating device towed by a tractor or the like has a plurality of soil cultivating units arranged in parallel on a work machine frame, each having a pair of left and right cultivating blades that curve upward toward the rear. It is designed to cultivate straw crops with the opposite cultivating blades.
By the way, the soil cultivation work is carried out when the crop grows and grows to a certain extent from the ground surface (generally referred to as conventional culture soil), and before the buds emerge from the ground surface (generally referred to as early soil cultivation). There is.

As a unit for early cultivating work that is performed before crops sprout from the top of the culm, a cultivating unit having a kamaboko-shaped curved pressing plate surface covering both sides from the top of the culm is known.
However, this type of early soil cultivating unit cannot be used for conventional soil cultivating work because the crop is pushed down or cut by the pressing plate surface when the crop is out of the surface.

  Therefore, the conventional soil culturing work when the crop is extended from the ground surface uses a soil cultivator unit in which a predetermined gap or space is formed between the opposite rear ends of the left and right soil cultivator units. Is not affected. However, this cultivator unit cannot cultivate the top of the crop around a smooth surface. For this reason, the surface of the top of the ridge becomes an uneven surface, the surface area becomes large, and the amount of the herbicide increases because the herbicide does not spread smoothly, resulting in inefficiency in both cost and labor. Therefore, it is inconvenient for early cultivation.

For this reason, in the past, the cultivator unit was used properly according to the early cultivating work and the customary cultivating work. To that end, it is necessary to provide a cultivator unit for each work, and each cultivator unit according to the work. Since it had to be replaced, a lot of time and labor were spent on the replacement work.

It is also conceivable that an extension blade such as a rubber plate can be detachably attached to the rear end of the right and left soil ridger unit. It is intended for expansion, and is installed in the vertical direction, similar to the soil wing plate. For this reason, even if the gap between the extension blades is narrowed and the crop is made of a flexible material that does not damage the crop, the surface of the extension blade that is in contact with the ground surface near the top of the ridge is the thickness of the plate. Therefore, the extension wing plate merely upstands the ground at the top of the ridge to an uneven surface and cannot press the top with a smooth plate surface. Therefore, it is not possible to expect the effect of early soil cultivation in which the top of the ridge is smooth and the weeding efficiency is improved.

  Accordingly, a first object of the present invention is to provide a soil culturing apparatus that can be shared for early soil culturing work and conventional soil cultivating work by simply attaching and detaching members.

A second object of the present invention is to provide the above soil cultivating apparatus provided with an auxiliary vane plate that can be finely adjusted according to the shape and height of the top of the ridge and can adjust the pressing force to the ridge. It is to provide.

It is characterized by comprising an early cultivating auxiliary wing plate that presses the central top of the ridge to a smooth surface.

In order to achieve the second object, the common culturing device for conventional cultivating soil and early cultivating according to the present invention includes a vertical bracket in which the early cultivating auxiliary wing plate is attached to and detached from a rear end portion of the cultivating wing plate, and Longitudinal or lateral elongated holes formed in the rear part of the soil wing plate and two lateral or longitudinal lengths formed in the longitudinal bracket, which are integrally joined with the top portion cultivating plate having a flat surface extending laterally. It is characterized by being able to variably couple the top and bottom, front and rear positions of the ridge top cultivating plate and the opposing angle to the ridge top with respect to the cultivating wing plate according to the bolt connecting position between the holes.

In order to achieve the third object, the common culturing apparatus for conventional cultivating soil and early cultivating soil according to the present invention further includes the early cultivating auxiliary wing plate having a longitudinal or lateral length at the rear of the cultivating wing plate. A vertical plate that can be slidably attached up and down and back and forth through a hole, and a vertically inclined plate formed with a fulcrum engaging portion and a circular arc hole centered on the fulcrum engaging portion outside the vertical plate are integrated. A bracket having an upper surface, an engagement support shaft that is supported by a fulcrum engaging portion of the vertical tilt plate of the bracket, and a pin hole that is fixed at a variable rotation angle along a circular arc long hole of the vertical tilt plate. It is composed of a ridge top culture plate that protrudes in the opposite lateral direction with its lower surface curved in a convex shape toward the rear.

The soil culturing apparatus according to the present invention is based on a conventional soil cultivator unit in which a predetermined gap or space is formed between the rear ends of opposing soil culturing blades of the pair of left and right soil culturing units. When cultivating upward from the ground surface, it is possible to perform conventional cultivating work without damaging crops, and by using auxiliary wing plates attached to each of the posterior ends of the cultivated wing plates, Is supplemented by a substantially horizontal plate of auxiliary blades extending in the lateral direction, and the top portion is pressed against the bottom surface of the auxiliary blade plate extending in the front-rear direction to form a smooth soil surface necessary for early soil cultivation. Is done.
Therefore, the soil culturing apparatus of the present invention can be used for both early soil culturing and conventional soil culturing simply by attaching and detaching the auxiliary blades.
